PLAITING ATTACHMENT FOR 'SEWING-MACHINES.

SPECIFICATION forming part of Letters Patent No. 264,147, dated September 12, 1882.

Application lcd July 19, 1882. (No model.)

To all whom it may concern:

Be it known that I, GrMoN S. GOLDMAN, of Syracuse, in the county of Onondaga, in the State of New York, have invented new and useful Improvements in Plaitin g Attachments for Sewing-Machines, of which the following, taken in connection with the accompanying drawings, is a full, clear, and exact description.

This invention consists, first, in improved devices designed to better secure a hemmer or tucker in its requisite operative position on a sewingmachine, and adapted for any location of the clamping-screw with which sewing-machines are usually provided for attaching hemmers and tuckers thereto; and, secondly, in a novel construction and combination of the constituent parts of the tueker, whereby thesame is rendered more convenient and efficient in its operation than others heretofore in use, all as hereinafter more fully explained, and specitically set forth in the claims.

Referring to the annexed drawings, Figure 1 is a plan view of my invention in its operative position. Fig. 2 is an edge view of the same. Fig. 3 is a transverse section on lineX X. Figs. 4 and 5 are detached plan views, respectively, ofthe main plate and the gageplate. Fig. Gis a plan View of the clasp by which the aforesaid plates are secured to each other adjustably in their relative positions. Fig. 7 illustrates the adaptability of my inven tion for the 'various locations of the thumbscrew or clamp-screw by which it is to be attached to the machine. Fig. 8 illustrates modifications of the means for attaching the 'flicker or hemmer to the sewing-machine; and Fig. 9 is a plan view of my improved attaching devices applied to a hemmer.

Similar letters of reference indicate corre! A represents the main plate, provided on one end with the rigid transverse hook o for the reception of the edge of the tuck to be stitched, as hereinaftermoreparticularlysetforth. Said plate has on its upper surface two graduated scales, p and t, one of which is on the rear edge and arranged from the hooko toward the opposite end of the plate, and preferably divided into spaces of one-sixteenth of an inch each. The other scale is at the front edge of the plate and divided into spacesof one-eighth inch each, the numbering of the latter scale beginning with number 1, directly opposite number 3 ofthe rea-r scale. The plateAis also provided on one edge with a series of notches or ratchet-teeth, d, and the gage-plate G, which is situated underneath the main plate, is provided on the opposite edge with similar notches, g. The gage-plate G is movably connected to the main plate A by means of aclasp, F, which encompasses the two plates, and is provided on its top with two ways, it', preferably formed of lugs punched out of the edges of the clasp and bent over the top of the same. In the said ways slide two plates, f and h, which overlap respectively opposite edges of the main plate and gage-plate, and are provided with a tongue, u, as best seen in Fig. 3 of the drawings, by which tongue they engage the notches d and g of the plates A and G.

On the end of the clasp F, facing the hook o ofthe main plate A, is hinged a lip, l, which is somewhat wider than the main plate, so as to project at opposite edges thereof. The lip Z is pressed against the under side of the gageplate by a spring, m, secured to the under side of the clasp F and bearing with its free end on the bottom of the lip. The end of the gageplate Gr which lies between the main plate A and lip Z is provided with lateral extensions, one of which projects at the rear edge of the main plate, and has a forwardly-extended lip, n, which, in conjunction with the lower lip, l, forms the hook or groove for the reception of the edge ot either the hem of the garment or the tuck already formed. The other lateral extension of the gage-plate projects at the front edge of the main plate and forms a gage or indicating-arm, s, its forward edge being even with the end ofthe gage-plate and lying across a graduated scale, r, on the edge of the lip l, said scale being divided into one-sixteenthinch spaces, for the purpose hereinafter explained.

The main plate A is provided at the end adjacent to the hook o with the extension E, which has three means, e e c', for detachably connectingthereto two bars, da. Said means may consist either of holes for receivingthe hooked end of the bars, as shown' in Figs. l and 2 of the drawings, or of studs or hooks for engaging an eye on the end of said bars, as represented in Fig. 8. The arrangement ofthe three attaching devices e e c allows the bars to be extended from the main plate, either in line IOO 2 264i, lli? therewith, as shown in Figs. l and 8 of the drawings, or at an angle therefrom, as shown in Fig. 7, thus accommodating the device to the location of the clamp-screw S, with which nearly every machine is provided. One of the bars a has a laterally-extended shoulder or ledge, b, and the other bar c lies across said shoulder, and is provided with a series of notches or a ratchet, c, adapted to engage with the same. The clampscrew S then being introduced between the two bars a a, and pressing one upon the other, firmly secures the same in the desired position. An equivalent arrangement is illust-rated in Fig. 8 of the drawings, in which both bars are provided with a ratchet-face, and a washer, c, is placed astride the same, and has a downward angc engaging the ratchets of the bars, and the clamping-screw S passes through the said washer.

and firmly secures the same interlocked with the bars c a.

It is obvious that the described attaching devices are applicable to a liemmer, as shown in Fig. f the drawings, as well as to a tucker, as before described.

The operation of my invention is as follows: The tncker is secured in position by connecting the bars a a to the main plate A and clam p` ing said bars by the set-screw S, which enters a hole in the top ofthe sewing-machine table. The width of the tuck to be formed is regulated by placing in range with the needle the mark of the scale p corresponding to the width of the tuck desired. The first tuck is gaged by placing the hem of the garment against the end of the gage-plate G and between the lips la, then spreading the fabric under the main plate and into the hook 0 thereof. The fabric is thus passed under the needle. The fabric beingmaintained smooth under the main plate causes the row of stitches to be parallel with the edge of the garment and with the tuck in the hook 0. When this is completed the fabric is removed from under the tucker. Then the gage-plate is set at a distance from the hook o corresponding to the distance required between the tucks, the scale ton the main plate, in conjunction with the indicators on the gage-plate, serving to indicatethe said distance. Before clamping the two plates A and G the clasp F is moved backward or forward to bring the end of the lip l the same distance from the end of the gage-plate as the distance from the seam ot' the tuck to the edge of the tuck already formed, as aforesaid, theindicators being therefore set on the scale 9^ of the lip lto correspond to the number of the scale p which was in range with the needle during the formation of the tuck. The parts being then locked in their desired position by the plates fand h, the tuck is introduced between the lips Z and u, the fabric again spread under the main plate and tucked into the hook 0, and then passed under the needle in the manner aforesaid, thus formingtucks of uniform widths with the greatest facility and accuracy. rIhe peculiar arrangement of the flexible lip lallows diiferent thicknesses of seams to pass underneath the tucker without interfering with the operation of the device.

It will be observed that owing to the arrangement of the main plate A, with its fixed hook 0 and gage-plate G, and adjustable lip I., I am enabled to form tucks of any desired width and at almost any distance apart.

Having described myinvention, whatI claim 1sl. In a hemmer or tucker attachment for sewing-machines, the combinationmwith the main plate A of said attachment, of two bars connected therewith and interlocking ratchets applied to the' free end of said bars and clamped by the attaching-screw, substantially as set forth and shown.
